|m+3|=13

Lösung

∣ m + 3 ∣ = 13

m = - 16 or m = 10

Schritte zur Lösung

∣ m + 3 ∣ = 13

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

m + 3 = - 13 or m + 3 = 13

m + 3 = - 13 or m + 3 = 13

m = - 16 or m = 10

∣ x - 5 ∣ = 5 x + 3

∣ x + 5 ∣ + 9 = 8

∣ - 3 x ∣ + 4 = 7

∣ 2 x + 7 ∣ + 2 = 11

x^{2} - 2 x - 4 = 4
